Anyone have the schematic to this amp?

Someone has been in here prior to me and mucked around with it. theres some replaced transistors in the power supply area that arnt even in the right holes, probably not even the right transistors.

One of those transistors reads shorted.

All the outputs and power supply outputs read fine. Plus the bridge rectifier is clobbered up, like its missing, and 2 TO-247s just tacked in place of where the bridge used to be.

Like i said, its all mucked up. Any help would be appreciated.

i got it running. one channel is totally fine but the other one is distorted.

the base of both drivers and both outputs on the bad channel is roughly between 8 to 10v DC bouncing around. scope shows the signal, but noisey and shifted above 0v.

caps test fine in that circuit.

Other channel perfectly fine.
